However, these drugs have problems such as insufficient pharmacological effects and many side effects, and the development of more effective and safe therapeutic agents is desired.
そこで、 近年、 平滑筋細胞におけるカリウムチャネル活性化作用という新しい メカニズムを持った平滑筋弛緩薬が開発され、 循環器系疾患や気管支疾患の治療 薬として注目を浴びている。 このような治療薬の有効成分であるカリゥムチヤネ ル活性化作用を有する化合物としては、 クロマカリム [ (土) —トランス一 6— シァノー 2, 2—ジメチルー 4— ( 2 —ォキソピロリジン一 1 一ィル) 一 3, 4 ージヒドロ一 2 H— 1—べンゾピラン一 3 —オール] 等が知られている。  Therefore, in recent years, smooth muscle relaxants having a new mechanism of activating potassium channels in smooth muscle cells have been developed, and are attracting attention as therapeutic agents for cardiovascular and bronchial diseases. Compounds having an activity of activating caldicum cyanel, which is an active ingredient of such a therapeutic drug, include cromakalim [(sat) -trans-6-cyano-2,2-dimethyl-4- (2-oxopyrrolidine-11-yl) -1 3,4 dihydro- 1 H- 1-benzopyran-1 3-ol] and the like are known.

Therefore, an object of the present invention is to provide a compound having a calcium channel activating action which is excellent in both efficacy and safety. Disclosure of the invention Thus, the present inventors have synthesized and screened a large number of compounds using the activity of the potassium channel as an indicator, and found that a 4-quinolinone derivative having a specific structure or a salt thereof has a strong activity of the activation of the potassium channel. However, they have found that they are also useful as medicaments for treating cardiovascular diseases and bronchial diseases, and have completed the present invention. That is, the present invention provides the following general formula (1):

The tension was recorded isometrically on a recorder via an FD transducer and a dynamic strain meter. Elapsed 6 0 minutes or more after the suspension, the specimen is stabilized, was applied several times a noradrenaline 1 0- 7 M. Under noradrenaline 1 0 one 7 M contracts, applying the acetylcholine 1 0- 7 M, were used in the experiment the specimen relaxation is not expressed as inner skin剝離specimen. K + 3 OmM was applied, and when the contraction was constant, samples (compounds with the compound numbers shown in Table 20 and cromakalim) were applied cumulatively at 10-minute intervals, and the 50 % inhibitory concentration (IC 50 ) was applied. Was calculated. Incidentally, applying the Papabe phosphorus 1 0- 4 M, it was confirmed 1 0 0% relaxation. Each sample is dissolved in dimethyl sulfoxide and (5 X 1 0- 2 M) , was used by diluting with pure water.
